"""BRK06 — Opening-Range Breakout (daily).

HYPOTHESIS: On 1d bars, go LONG when today's close > prior-day high (expansion/gap breakout).
SL = prior-day low. max_bars = configurable (3 or 5). No short side (breakdowns symmetric but
crypto skew is upward; testing long-only first). Entry at close[i] once close[i] > prior high[i-1].
Exit at SL=prior_low[i-1] or max_bars (time stop), whichever first.

Grid: max_bars in {3, 5} -> 2 configs × 1 TF × 2 assets = 4 backtests.

Honesty rules:
- decision uses close[i] vs high[i-1]: CAUSAL (prior-bar high is known by close of bar i).
- SL = low[i-1]: known causal.
- entry = close[i] (not high/low extreme of bar i).
- fee = 0.10% RT (Deribit taker).
